The starting point of this work is the RMF framework in the Berggren basis.
This relativistic many-body method with nucleons as degrees of freedom allows us to generate effective spherical mean-field potentials for each isotope considered
using a single nucleon-nucleon interaction.
These spherical potentials are then used to fix the parameters of Woods-Saxon (WS) potentials where quadrupole deformation can be explicitly included,
and whose resonant spectra can be determined using the Dirac equation for deformed systems.
Here, we use the NL3 interaction [1]}, which is given by the parametrization of an effective nonlinear Lagrangian density of relativistic mean field theory,
and which provides a good description of both nuclei at and away of the valley of \(\beta \)  stability.
